Parameter Description
Peripheral surface Y: The positions refer to the reference point:
C0 Positioning angle for machining surface – (only for single position)
Y0 Reference point Y – (only for single position)
Z0 Reference point Z – (only for single position)
X0 Reference point X – (only for single position)
(only for Shop-
Turn)
∅ Diameter of pocket
Z1 Pocket depth (abs) or depth relative to Z0/X0 (inc) – (only for ∇, ∇∇∇ and ∇∇∇ edge)
DXY
Maximum plane infeed
•
Maximum plane infeed as a percentage of the milling cutter diameter
•
- (only for ∇ and ∇∇∇)
DZ Maximum depth infeed - (only for ∇, ∇∇∇ and ∇∇∇ edge)
UXY Plane finishing allowance - (only for ∇, ∇∇∇ and ∇∇∇ edge)
UZ Depth finishing allowance – (only for ∇ and ∇∇∇)
Insertion Various insertion modes can be selected – (only for plane-by-plane machining method
and for ∇, ∇∇∇ and ∇∇∇ edge):
Predrilled (only for G code)
•
Vertical: Insert vertically at center of pocket
•
The tool executes the calculated depth infeed vertically at the center of the pocket.
Feedrate: Infeed rate as programmed under FZ
Helical: Insert along helical path
•
The cutter center point traverses along the helical path determined by the radius
and depth per revolution. If the depth for one infeed has been reached, a full circle
motion is executed to eliminate the inclined insertion path.
Feedrate: Machining feedrate
Note: The vertical insertion into pocket center method can be used only if the tool
can cut across center or if the workpiece has been predrilled.
Clamp/release spindle (only for end face C/peripheral surface C, if inserted vertically)
The function must be set up by the machine manufacturer.
(only for Shop-
Turn)
FZ Depth infeed rate – (for vertical insertion only)
(only for G code)
FZ Depth infeed rate – (for vertical insertion only)
(only for Shop-
Turn)
EP Maximum pitch of helix - (for helical insertion only)
The helix pitch may be lower due to the geometrical situation.
